Technical Field
[0001] The present invention relates to an automatic machine for processing a tooth by a
bone graft material and, more particularly, an automatic machine for processing a
tooth by a graft material that can supply a reagent and sterilized distilled water,
which can control the contents of organic substances and inorganic substances, in
a predetermined amount, with a powder type or a block type graft material in a container,
and that includes a heat generator and vibrator for rapidly manufacturing a graft
material.
Background Art
[0002] The present invention relates to a machine that automatically manufactures a tooth
bone graft material that is used for dental implantation and guided bone regeneration
(GBR).
[0003] Usability of a tooth bone graft material has been reported as being successful in
many theses and clinical tests, but there is a problem that it is required to entrust
enterprises having special facilities in order to make a tooth bone graft material,
it takes long time to manufacture a tooth bone graft material due to manual work in
the related art, and the cost for transportation is high, so it is difficult to operate
on a patient in a short time.
[0004] Further, there are two purposes of using a tooth bone graft material. The first purpose
is to restore the original shape of a collapsed alveolus by restoring the alveolus
after extraction of a tooth. This is for preventing a loss of volume of a graft material
while a new bone grows by increasing osteoconduction using a bone graft material containing
a large amount of inorganic substances, thereby restoring a collapsed alveolus. The
second purpose is to improve osteinduction that reduces bone restoration time by inducing
bone growth factors, by implanting a tooth bone graft material containing a large
amount of organic substances into the part with the alveolus removed, which is not
related with a loss of volume of a tooth bone graft material, to be absorbed into
the existing alveolus in a short time.
[0005] In the related art, tooth bone graft materials are manufactured through a predetermined
series of simple processes, regardless of the contents of inorganic substances and
organic substances in the tooth bone graft materials. When these graft materials are
used, medical institutions that treat injured alveoli cannot estimate a reduction
ratio of volume of the graft materials and osteinduction, so they inject an excessive
amount of graft material. Accordingly, patients who have had the operation have to
stand a pain for a long period of time and the next step of the operation cannot be
performed due to slow osteinduction.
[0006] Therefore, there is a need for an automatic machine for manufacturing a tooth bone
graft material that can control the contents of inorganic substances and organic substances
in a tooth bone graft material in consideration of osteinduction and osteoconduction,
and that reduces the manufacturing time through an automated manufacturing process.
[0007] As a countermeasure against the problems, a "method for producing tooth bone graft
materials" that uses ultrasonic waves under vacuum has been disclosed in
Korean Patent No. 10-1163594. This patent has a problem in that it is difficult to keep a vacuum state while sequentially
putting tooth bone graft materials into a chemical, it takes a predetermined time
to make a vacuum state again, and graft materials are necessarily formed in a block
shape, as in the related art.
[0008] Further, block-shaped graft materials containing a large amount of organic substances
are low in strength, so they cannot keep the volume after being implanted and are
absorbed too quickly, so the treatment purpose cannot be achieved. Furthermore, 80~90%
of graft materials for a lost bone are generally used in a powder type, so there is
a need for an automatic machine for powder type graft materials.
[0009] In addition, since tooth bone graft materials are supposed to be implanted into a
human body, there is a need for measures against bacterial contamination in the manufacturing
process.
[0010] Therefore, there is a need for an automatic machine processing a tooth by a bone
graft material that can use a powder type graft material, can control the contents
of organic substances and inorganic substances in a graft material, and can prevent
bacterial contamination due to manual work in the manufacturing process.

by a bone graft material, seen at another angle, FIG. 3 is a view showing in detail
a graft material receiving container 53 and a cylinder 55, and FIG. 5 is a view showing
components of the present invention and a control flow
[0030] The present invention includes: a body 10 that includes a power supply 60 supplying
power to a controller that controls the amount of supply solution, and a suction pump
40 and a vibrator 80, the body 10 having a receiving space defined by a frame; a receiving
container 53 that is disposed in the receiving space, has a space for keeping a tooth

70.
[0031] The present invention further includes a heat generator 54 that covers the cylinder
55 and the supplying container 20 to heat the supply solution therein.
[0032] The heat generator 54 heats the solution in the cylinder 55 and the supplying container
20 in the processes of washing, sterilizing, removing inorganic substances, removing
fat, and removing protein and keeping the temperature of the solution in the cylinder
at 61∼120□ for 10 seconds to 60 minutes.
[0033] A solenoid valve that allows for and blocks the supply solution may be disposed in
the inlets 56 and the outlets 57 of the cylinder 55. The solenoid valves operate in
response to a control signal from the controller.
[0034] The supplying container 20 keeps a reagent for the manufacturing process of a graft
material, such as sterilized distilled water, trichloromethane, ethyl alcohol, hydrogen
peroxide, citric acid, hydrochloric acid (Hcl), sulfuric acid, phosphoric acid, malic
acid, trichloroacetic acid, sodium hypochlorite (Naocl), sodium hydroxide (naoh),
and glacial acetic acid, and a mixture of the reagent.
[0035] Further, the supplying container 20 may be positioned higher than the cylinder 55
to smoothly supply the supply solution.
[0036] For a finer supply of a reagent, a fixed-quantity pump 30 that supplies the supply
solution in the supplying container 20 in a predetermined amount may be further provided
between the supplying container 20 and the cylinder 55.
[0037] The fixed-quantity pump 30 supplies a necessary amount of supply solution to the
cylinder 55 so that an operator can control the contents of inorganic substances and
organic substances in accordance with the purpose of an operation.
[0038] The controller may control whether to open/close the solenoid valves, whether to
operate the fixed-quantity pump, the control method of the fixed-quantity pump, whether
to operate the suction pump 40, and determine control and frequency of vibration of
the vibrator 80 in order to control of the supply solution, and may inform a display
of the operation states of the components and related information.
[0039] In order to accelerate washing and sterilizing, in addition to putting a graft material
into a chemical, the vibrator 80 may include a vibrator directly fastened to the cylinder
55 and using an electromagnet, and a spring 81.
[0040] The spring 81 can be replaced by damping rubber or an elastic member.
[0041] The magnetic vibrator 80 generates vibration of 1 to 100,000 VPM (Vibrations per
Minute, the number of vibrations of an electromagnet per minute), is directly connected
to the cylinder, and has an oscillating wave higher than ultrasonic waves used in
the related art, so the manufacturing time can be reduced.
[0042] The cylinder 55 and the receiving container 53 need to be made of a material that
suppresses habitation of bacteria, viruses, and molds, has chemical resistance against
the supply solution, and a heat resistance against generated heat.
[0043] FIG. 4 is a view showing the receiving container 53 in detail.
[0044] In order to process a powder type graft material, the present invention has a space
for keeping a tooth graft material to keep a powder type graft material formed by
crushing a tooth graft material and includes the net 59 through which a supply solution
flows inside and the cover 51 having the handle 52 for convenient work.
[0045] The net of the receiving container 53 has fine holes of 1 to 2,000 micron to smoothly
receive and discharge the solution in the cylinder 55.
[0046] The net 59 may have a shape inclined to a side or a semispherical shape to easily
discharge a supply solution.
[0047] FIG. 6 shows an automatic manufacturing process of the present invention in a process
of manufacturing a tooth bone graft material. As shown in FIG. 6, according to the
present invention, all processes of removing a chemical after washing in a process
of removing inorganic substances or processes of removing organic substances are automatically
performed.
[0048] Manufacturing processes of the present invention are described in detail. A method
of removing organic substances and inorganic substances from a tooth graft material
is described in detail in
KR 10-2012-0144121 by the inventor(s).
[0049] The steps of primary sterilizing and removing foreign substances are to remove germs
on a tooth and to perform primary sterilizing by putting the tooth in hydrogen peroxide
(3~35%) for 1 minute to 10 hours in order to remove tartar on the tooth and soft tissue.
[0050] A designing step and a boring step are used only for a block type. The designing
step involves cutting a graft material in a shape appropriate to a part wherein a
tooth has been removed and the boring step is to form fine holes (30-80 holes for
one graft material) in a predetermined rectangular pattern of 0.5~0.8mm using a laser
or a drill to process a cancellous bone. The fine holes help the action of a chemical
and makes designing easy when the graft material is implanted into the bone inside
a gum (alveolus).
[0051] A coating step is to prevent a supply solution to be supplied in order to ensure
a cortical bone. The coated portion of the cortical bone further suppress the action
of a chemical, as compared with the cancellous bone) in the machining process. A coating
material in this step is a material having adhesiveness and a stable chemical structure.
Further, the material does not influence the machining chemical.
[0052] A crushing step, which makes a graft material into a powder type, crushes a tooth
in an appropriate graft material size.
[0053] A powder type or a block type graft material that has undergone the steps is put
into the receiving container 53 and then the receiving container sealed with the cover
51.
[0054] The sealed receiving container 53 is put into the cylinder 55 and then the automatic
machine is operated.
[0055] The controller controls the fixed-quantity pump 30, the vibrator 80, the heat generator
54, the suction pump 40, and the solenoid valves in accordance with a predetermined
program and settings of the controller 11.
[0056] In a step of removing inorganic substances or removing organic substances, when it
is a powder type, citric acid, hydrochloric acid (Hcl) of 1~50%, sulfuric acid, citric
acid of 1~20%, phosphoric acid, malic acid, and trichloroacetic acid may be independently
used of their mixtures may be used to remove inorganic substances, whereas sodium
hypochlorite (Naocl) of 1~99%, sodium hydroxide (naoh) of 1~99%, and glacial acetic
acid may be independently used or their mixtures may be used to remove organic substances.
[0057] When it is a block type, in the step of removing inorganic substances, the concentration
of hydrochloric acid may be in the range of 1~50% to adjust Ph of the citric acid
(1~20%).
[0058] A solution that is supplied to the cylinder 55 is a chemical having a volume of 2-40
times of the volume of a graft material, and inorganic substances or organic substances
are removed from the powder by the magnetic vibrator 80 at 100- 100,000VPM (the number
of vibrations of an electromagnet per minute) for 1-20 minutes. The process is kept
until 1~50% of calcium or collagen remaining in the power is removed. Heat of 61~120□
is applied to the receiving container 53 for 1 to 20 minutes by the heat generator
54.
[0059] In a step of removing a coating, the coating is removed by vibration within 1 to
50 minutes after the step of removing inorganic substances is started. A coating material
in this step is a material having adhesiveness and a stable chemical structure. Further,
the material does not influence the machining chemical.
[0060] In a chemical removing step and a vacuum suction step, the supply solution in the
cylinder 55 is discharged to the discharging container 70 by opening the solenoid
valves in the outlet 57 and operating the suction pump 40.
[0061] In a washing step, sterilized distilled water is supplied by 2-40 times the volume
of the graft material and then washing is performed with vibration of 100 ~ 100,000VPM.
Further, heat of 61 ~ 120□ is applied to the cylinder for 1 to 20 minutes.
[0062] In steps of removing fat and protein, the sterilized distilled water is discharged
and then the chemical with fat and protein removed is supplied to the cylinder. A
chemical containing trichloromethane and ethyl alcohol that are 2-40 times the volume
of the graft material is supplied, and fat and protein are removed by vibration of
100~100,000VPM. Further, heat of 61 - 120□ is applied to the cylinder for 1 to 20
minutes.
[0063] In a sterilizing step, hydrogen peroxide of 2-40 times of the volume of the graft
material is supplied, and fat and protein are removed by vibration or 100~100,000VPM.
Further, heat of 61 - 120□ is applied to the cylinder for 1 to 20 minutes, and then
the chemical is discharged.
[0064] A graft material is manufactured in the shape that an operator wants through third
to tenth washing steps in the step of removing inorganic substances of the present
invention.
[0065] The manufactured graft material is directly used for a patient, or kept after freezing/drying
and sterilizing.
[0066] According to the present invention, it is possible to manufacture not only a block
type tooth graft material, but a powder type tooth graft material.
[0067] Further, all processes are automatically finished after determining the type of a
tooth bone graft material, putting it into a receiving container, and then putting
the receiving container in a cylinder, the manufacturing time is 1/3 to 1/10 of that
of the related art by a magnetic vibrator. Accordingly, a tooth bone graft material
can be manufactured within about 25 minutes, so it is possible to directly operate
a patient after machining a tooth pulled out from the patient.
[0068] Further, the present invention provides automated equipment, so it is possible to
machine a tooth bone graft material without being exposed to external contaminants.
Industrial Applicability
[0069] The present invention is available for a machine that automatically manufactures
a tooth bone graft material that is used for dental implantation and guided bone regeneration
(GBR).
